You can’t get there from here.
Are you a robber or being robbed? Did the Yankees win over the Red Sox or lose to them? Does fish oil provide omega acids or the other way around? Some networks are inherently asymmetric, but we never talk about them—until now.
In this chapter, you will learn how to identify asymmetric relationships between items and build and handle directed networks. In the end, you will be able to check if a directed network is a directed acyclic graph, and if it is, establish a partial order of the nodes by performing a topological sort.
